Factory unlocked iPhone 3G, iOS 4 support tethering?

Some of us knows that during the 3.1.2 all iPhone Factory unlocked phone had their tethering disabled. and only when 3.1.3 came out, we got back our tethering option for Factory unlocked iPhones.
will tethering be available for iPhone Factory unlocked after iOS 4 update?
Thank you in advance

Allan
Your advice is about all I can think of doing. I have a friend in Milan that the phone can be sent back to. I have a funny feeling that when I get the phone back I'll have the same issues.....
I can get a antenna replaced here in the UK for about GBP60....but that would invalidate the warranty.
What is a lingering doubt over it being a hardware issue is why would it work perfectly with one contry's SIM and not anothers ?

I have a factory unlocked iphone 4s ios 5.1 and let me know if I can upgrade to ios 6?

I have a factory unlocked iphone 4s ios 5.1 and let me know if I can upgrade to ios 6?

The conclusion I have arrived at during the limited time I have been reading indicate that there is a growing number of people complaining about the iOS 6 upgrade. According to Apple tech support they currently have no fix for any of the issues and they indicated that there are a large amount of calls coming in.

Factory unlocked iPhone 4S ios 5.1.1 emoji is not working under some circumstances

I have a factory unlocked iPhone 4S
I have a $50 monthly 4g plan on tmobile but I doubt that is relevant
I am running iOS 5.1.1
Whenever I send emojis to other iPhones my recipients cannot see them unless it is on iMessage.
Even on the Facebook app, I can see emojis that friends send me in messages but when I reply with an emoji via facebook it says "message cannot be delivered at this time"
However one single emoji does work on Facebook and it is the red heart
Can someone help me fix this or at least tell me why it won't work?
I can see emojis fine but for some reason I can't send them. Not even on facebook

T-mobile is not a supported carrier of iphones and not all functions will work. this is probably the reason emojis will not work. Switch to At&T

Was it purchased from an official Apple Store, not a reseller? Only Apple Stores sell official factory unlocked phones. The others sell hacked to unlock phones, and the unlocking is unstable.
Try these steps, as needed:
1. Reset phone - press both home and on/off buttons for at least 10 seconds until the Apple logo appears.
2. Settings > General > Reset > Reset Network Settings.
3. Replace SIM card (and reset network settings again)
4. Restore Phone in iTunes using a backup
5. Restore in iTunes as new, without using a backup

How can i fix "the sim card inserted in this iphone does not appear to be supported " after restoring a factory unlocked iphone 4

The term "factory unlocked" has no meaning. Your phone was not legitimately unlocked. Contact the carrier it is locked to and find out if you can get it unlocked.

Upgrading to IOS 5 will lock factory unlocked iphone 4 or not??

I have an Iphone 4 with ios 4.3.3 bb 4.10.01 and its factory unlocked. If I upgrade it to a new Ios 5, will I loose my unlock??
I know that factory unlocked iphones dont loose unlock if they are upgraded but I heard that IOS 5 will lock the factory unlocked also.

You heard wrong. IF the device is officially unlocked by Apple, it will not be relocked. IF it was hacked to be unlocked, upgrading iOS WILL relock the device to the original carrier.

I bought a factory unlocked iphone 4s. it was working fine but when i upgraded it to iOS 5.1 it gave me "no sim" message. so when i tried to restore the iphone setting it is giving me now "ICCID: unknown" message please help. any ideas?

Please define "factory unlocked". The term is basically meaningless. iPhones are sold either carrier locked or unlocked. Some carriers will unlock them after a period of time upon meeting certain requirements and paying a fee.
There are lots of places that will "factory unlock" an iPhone. This basically translates to "hack". This can cause permanent damage to the phone. Best case scenario is these phones will re-lock to the original carrier on an update or restore. Worst case it they become expensive bricks.
ICCID unknown indicates a critical failure. There is no way to resolve this other than taking it in to Apple and getting the phone replaced. It's very possible that the phone was hacked and attempting to update has now killed it.
Where, EXACTLY, did you get this phone?

If I update my factory unlocked iphone 4 to iOS 7, will it have to be unlocked again?

Hi, I have an iphone 4 factory unlocked running iOS 6.1.3, if I update it to iOS 7, will I have to pay to get it unlocked again or will it still be unlocked for use afterwards?

okay, but just to be safe, how can we be sure that our phone is fatory unlocked? because my cousin apparently had a factory unlocked iphone 3g and updated it iOS 6.1.3 and it got locked
Your cousins phone was therefore not, in fact, factory unlocked. An iPhone sold directly by Apple as unlocked will never lock because of an iOS update.
An iPhone unlocked by going through proper procedures and channels with the carrier to whom it was originally locked will never lock again because of an iOS update.
An iPhone hacked to unlock it (which is unlocked by ANY other means then the first two) will lock again whenever iOS is updated.
If I had to guess, I would say 90% of privately sold iPhones sold as "unlocked" are in fact merely hacked to unlock them, and WILL relock when updated.
Some iPhones sold in Europe are also sold as "SIM free" and contract free, but do in fact lock to the carrier of the first SIM inserted in them. No contract, or "SIM free" does not mean unlocked.

Factory unlocked iPhone 4 now locked!!

Hey guys,
I bought this iphone 4 from uk, its a 32gb white factory unlocked iphone. MC606B. When i bought it there was no cydia or anyother app that suggested that it wud be a locked piece. I brought it to india and it worked fine. I just updated my iphone 4 from 4.3.3 to ios 5 and now it says that the sim card inserted in this phone does not appear to be supported!!! the error msg says SIM_LOCKED.
Is it possible for it to get locked again.
As far as i know all the MC606B builds r factory unlocked.
Plz help
what can i do about it??

Where in the UK did you purchase it?
The model number is NOT a reliable indicator of the carrier lock status.
If you did not purchase it from a corporate Apple Store, then it was probably hacked, not factory unlocked.

Ask All Your Factory Unlocked iPhone 4S Questions Here!

So here is the deal, I recently purchased a factory unlocked iPhone 4S from the Apple store and I am using it on T-Mobile with a micro sim that I got from T-Mobile. I have seen a few threads about this topic around the internet but I was weary of how the phone would work on T-Mobile. So, if you have any questions regarding this phone, feel free to ask them here and I will be happy to answer any questions that you may have if youre thinking of buying one yourself! This was an upgrade for me from an unlocked and jailbroken 3G 16GB.

I am looking to upgrade my Samsung Vibrant to the iPhone 4s and want to stay with T-Mobile. I live in Chicago and the only thing that has kept me back is the 3G. Now that Tmobile supports 1900mhz I plan on getting the unlocked phone and hope to use tethering.
Jlopez-
I too live in Chicago and I have been using the 4s on the T-mobile network since November. Everything works perfect: Facetime, iMessage, MMS, tethering (EDGE speeds) and push notifications. I think you're making the right decision in upgrading from the Vibrant to the 4s.
I am however anxiously looking forward to the 1900 mhz 2G refarming that is supposed to be taking place in the future. I did a little bit of research through Google searches and forums and found that T-mobile's 1900 mhz in Chicago operates on a frequency that is likely to be a candidate for one of the upcoming refarmed markets. Not sure how accurate the information is but I hope it's right. I couldn't find any speculation of dates other than late 2012 and in some cases late 2013. Hope this helps.

Need help with using Factory Unlocked iPhone 4 (GSM) in US

Hi all I have an factory unlocked iPhone 4 (GSM) which is bought overseas. I will come to the US soon but I don't know how can I continue using with the US carriers.
Any solution?

If it is truly unlocked, just sign up for a plan with AT&T when you get to the US and insert the MicroSIM. AT&T will not permit pre-paid plans on iPhones. T-Mobile will, but they are not a supported carrier and you will not get 3G data speeds, only Edge. Other features may not work correctly such as MMS messaging, FaceTime, etc.

Date Time issue factory unlocked iphone 4s

I have a factory unlocked iphone 4s bought in Apple store US and currently in India. In Settings -> General -> Date & Time, I am setting "on" Set Automatically. After some time say 2-3 hours, the time automatically moves back by 30 minutes. In India there is no daylight savings. I am forced to set "off" for the "Set Automatically" option and then choose the timezone, time to keep it to the correct time. Anyone facing this issue ? By setting it to "Set Automatically" on, my understanding is it should sync with the mobile provider ("Airtel"). Is this a bug in iOS ?

i have same problem i also went to apple store but the can not find any problem i don't know what to do ?
i hop it's just a sofware problem

Will Apple cover my factory unlocked iphone 3GS anywhere in the world?

Hello,
I'm planning on buying a factory unlocked iphone 3GS directly from the Apple Store in Hong Kong.
Will Apple cover my iphone with the warranty worldwide or only in Hong Kong?
Thank you.

What I meant to say is that technically, hardware-wise, almost all iphones 3GS are the same (I believe the models in mainland China don't have GPS?).
It's no WiFi in China. GPS used to be illegal in Egypt, but they changed the law recently.
Correct me if I'm wrong but I suppose that the carrier lock is a software lock, which can be removed (we've all heard about it), but gets reversed once you update to a new OS version.
Carriers can ask Apple to unlock particular phones. The next time the iPhone is restored via iTunes, new firmware will be downloaded from Apple and will display a message saying it has been unlocked. It will stay unlocked if updated. Unofficial unlocks (which can not be done on current iPhones) will re-lock if the iPhone is updated.
I know it is the way it is, but I believe most of you would agree that if you buy a telephone, you shouldn't be forced to go with one carrier or another. That is why when I pay for an unlocked phone, I pay much more, go get the freedom (without hacks) to choose the carrier I want (where in contrast I pay much less for calls and internet than with the exclusive iphone carrier).
It would be much easier for Apple if all iPhones were unlocked, and the same in all countries, but the carriers make a fortune from their exorbitant roaming charges, so where the country's laws allow, insist that Apple not make any unlocked iPhones available in their countries.
By the way, MMS is not something most people use. There are some statistics on the internet about the ratio of SMS to MMS and it was something like 10 to 1.
All the 3G and 3GS iPhones are capable of MMS, but the carriers have to support it.
